Adds missing fields for iSCSI volumes

[gwkunze]

Rollback Plan

If a change needs to be reverted, we will publish an updated version of the library.

Changes to Security Controls

None as far as I know

Description

This adds the missing fields chapAuthDiscovery, chapAuthSession, initiatorName, portals, and secretRef to the iSCSI volume mounts.

From my limited testing the changes work, but as my knowledge of iSCSI is next to non-existent I can only say the specs seem to be correctly generated.

I noticed from my diff my editor has removed some trailing whitespaces in some of the files I've edited. I hope that is not an issue.

In case this matters to someone, I didn't use any AI for the PR. (Not out of conviction, just couldn't be bothered to set it up on my computer)
